单词	tannin
释义	tannintan‧nin /ˈtænɪn/ (also tan‧nic acid /ˌtænɪk ˈæsɪd/) noun [uncountable] Word Origin WORD ORIGINtannin Origin: 1800-1900 French tanner; ➔ TAN1 Examples EXAMPLES FROM THE CORPUS It has some plummy fruit, with sufficient tannin for only £2.74. One of the problems we've had of late is the wine keeping too much tannin as it matures. Pastiche: This charming, mediumbodied red wine from Joseph Phelps offers plentiful fruit, admirable length and little tannin. Red wines are fermented at a higher temperature than whites to extract colour and tannin from the skins. The 1994, like all vintages, is a burly wine with loads of blackberry fruit and a good lashing of tannin. The best examples have a good balance of dry tannin and rich fruit. This process allows the harsh tannin to mellow and the wine to develop complexity. Those caterpillars that feed on older leaves, with a high tannin content, are less nutritious for the chicks. word sets WORD SETS► Chemistry acetate, nounacid, nounacidic, adjectiveacidify, verbactive, adjectiveadditive, nounagent, nounalchemy, nounalcohol, nounalkali, nounalkaline, adjectiveamalgam, nounantioxidant, noun-ate, suffixatomic number, nounbase, nounbauxite, nounbeaker, nounbenzene, nounbiochemistry, nounbitumen, nounbleach, nounbond, nounbonding, nouncalcify, verbcarbohydrate, nouncarbonate, nouncarbon dioxide, nouncarbonize, verbcatalyst, nouncaustic, adjectivechain reaction, nounchemical, nounchemical, adjectivechemical reaction, nounchemist, nounchemistry, nounchlorinate, verbcitric acid, nouncombustion, nounconcentration, nouncondense, verbcontaminant, nouncontaminate, verbcontaminated, adjectivecorrode, verbcorrosion, nouncorrosive, adjectivecrucible, nouncrystal, nouncrystallize, verbcyanide, nounDDT, noundecay, verbdecay, noundecompose, verbdegrade, verbderive, verbdetoxification, noundextrose, noundioxin, noundispersion, noundissolve, verbdistill, verbeffervesce, verbeffervescent, adjectiveelectrolysis, nounelectrolyte, nounelectroplate, verbemulsify, verbemulsion, nounenzyme, nounexpand, verbfatty acid, nounferment, verbferment, nounflashback, nounflask, nounformaldehyde, nounformula, nounfructose, nounfungicide, nounfuse, verbgas, noungaseous, adjectiveglucose, noungranular, adjectivegraphite, nounhallucinogen, nounhelium, nounherbicide, nounhydrate, nouninert, adjectiveinsoluble, adjectiveinsulin, nounion, nounionize, verblactic acid, nounlimescale, nounlitmus, nounlitmus paper, nounlitmus test, nounmethane, nounmixture, nounmolecule, nounneon, nounnerve gas, nounneutralize, verbneutron, nounnitric acid, nounnucleic acid, nounnucleus, nounnutrient, nounorganic chemistry, nounosmosis, nounoxidize, verboxyacetylene, nounoxygenate, verbozone, nounpart, nounpectin, nounpesticide, nounpestle, nounpetrochemical, nounpH, nounphotosynthesis, nounplasma, nounpolyunsaturated, adjectivepotash, nounprecipitate, verbprecipitate, nounprecipitation, nounproduct, nounprussic acid, nounquicklime, nounradioactive, adjectiveradioactivity, nounradiology, nounreact, verbreaction, nounreactive, adjectivereagent, nounresidue, nounretort, nounriboflavin, nounsalt, nounsaltpetre, nounsaturate, verbsaturated, adjectivesaturation, nounsaturation point, nounsemiconductor, nounsoft, adjectivesolid, nounsolution, nounsolvent, nounstability, nounstabilizer, nounstable, adjectivestarch, nounsteam, nounsucrose, nounsulphate, nounsulphide, nounsulphur, nounsulphur dioxide, nounsulphuric acid, nounsulphurous, adjectivesurface tension, nounsuspension, nounsynthesize, verbsynthetic, adjectivetannin, nountartaric acid, nounTNT, noununstable, adjectivevalence, nounvitamin, nounvolatile, adjectivevulcanize, verbwater softener, nounwater-soluble, adjectivewater vapour, nounwetting agent, noun a reddish acid used in preparing leather, making ink etc
